A teacher writes an inequality x divided by 6 < -2 on the board. Vincent incorrectly solves the inequality and obtains x <

scZoUnD [109]

The error Vincent made was that he only multiplied the left side of the inequality with 6 although he had to multiply on both sides

Step-by-step explanation:

Given inequality that the teacher wrote is:

$\frac{x}{6} -2$

Solving an inequality means that the variable should be isolated on left side of the inequality.

So multiplying both sides by 6

$6* \frac{2}{6} < -2 * 6\\x < -12$

Vincent got the answer is x<-2 = > The error Vincent made was that he only multiplied the left side of the inequality with 6 although he had to multiply on both sides

Solve the following equation <br><br> 2x-y=17<br> X-y=10

Oduvanchick [21]

You can isolate y on both sides, getting:
2x-17=y and x-10=y

Then, make the two y equal each other, and solve the equation
2x-17=x-10

The answer would be x=7.
then, plut in the amount into one of the equations:
x-y=10
7-y=10
y=-3
T

Therefore, the answer is x=7 and y = -3, or (7,-3)
